This invention relates to a dispensing means for powder.

It is primarily aimed to provide a novel device which may be used in theform of of an attachment for a bottle or other container and which willrapidly and accurately dispense in predetermined quantities.

The more specific objects and. advantages will become apparent and inpart pointed out in the description following taken in connection withaccompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a view showing the attachment in elevationas mounted on a bottle, the latter being shown primarily 1n section,

Figure 2 is a vertical sectlonal vlew throu h a bottle and theattachment the same eing taken on the line 2-2 of Figure 1, and

Figure 3 is a horizontal sectional v1ew taken on the line 3-3 of FlgureReferring specifically to the drawings, 10 designates a bottle orconventional contalner for powder or the like which has ad acent themouth, an annular bead 11 and spaced beads 12 above the same.

The dispensing body 13 is attachable to the bottle and has a dependingcollar 14 provided with spaced apart inwardly extending lugs 15, suchlugs being adapted for downward movement between lugs or members 12, andthen to be turned so as to underlap the same as shown in the drawings,thus detachably securing the device to the bottle. Within the collar 14a suitable gasket 16 is carried for sealing engagement with the top ofthe bottle.

The body 13 has a horizontal wall 17 against which the gasket 16engages. De pending from wall 17 is a lower cylinder 18 while an uppercylinder 19 extends upwardly from such wall 17, being of greater di- 45a-meter than the cylinder 18 in order to provide a shoulder at 20. Adischar e spout 21 leads from the interior of cylinder 19.

The upper end of cylinder 19 is closed by a screw threaded plug or cap22. Slidable within the cylinders 18 and 19 is a discharge valve head23, the same having an annular flange 24 adapted to seat on the shoulder20. Screw threaded to the valve head 23 at 25 is a rod 26 which extendsslidably through the cap 22 and above the same has an operating knob 27screwed thereto. An expansive spring 28 surrounds rod 26 and abuts theunder surface of cap 22 and the upper surface of valve head 23. Thelower surface of valve head 23 is inclined at 29 toward the dischargespout 24.

A rod 30 is screw threaded to the valve head 23 and depends therefromand has a cut-off disk 31 screw threaded thereto and held againstaccidental displacement by a lock nut 32.

By reason of the construction described, if the bottle 10 be filled withpowder and inverted, and the knob 27 pulled downwardly, the Valve heads23 and 31 will move forwardly against the tension of spring 28, theValve 31 serving to cut off the quantity of material which enters thecylinder 18 and the valve 23 serving to discharge the same. Attention iscalled to the fact that the valve 31 by reason of its screw threadedconnection to rod 30 is adjustable to vary the quantity of materialwhich may enter the cylinder 18 upon each operation.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

We claim as our invention A dispenser attachment of the class described,comprising a body, said body including an annular horizontally disposedwall provided with means to attach it to a bottle or the like,'cylinderson opposite sides of said wall and of different dimensions providing ashoulder, one of said cylinders provided with a discharge opening, theother cylinder being adapted to receive material, a valve operable inthe cylinders and having an annular flange adapted-to seat on saidshoulder, a cut-ofi valve carried by the first mentioned valve andmovable into one of the cylinders, a stem extending from the firstmentioned valve, and a spring surrounding said stem and urging the firstmentioned valve into engagement with the shoul- In testimony whereof weafiix our signatures.
